GAGE-COCK.

, Specification of Letters Patent. Patgnted Jung 18, 1912.

Application filed December 16, 1911. Serial No. 666,223.

To all whom it may concern:

Be it known thatI, CARL EDWARD ANGIER,

.a citizen of the United States, residing at Beardstown, in the countyof Cass and State of Illinois, have invented certain new and usefulImprovements in Gage Cocks, of which the following is a specification,reference being had to the accompanying draw Ilfy invention relates tonew and useful improvements in water or steam gage cocks and has for itsobject to provide a device of this character with improved means foropening and closing the valve thereof.

A further object of the invention resides in the provision of a deviceof this character wherein the valve is held in its closed position bymeans of a spring, and a further ob ject resides in the provision of acam face on the valve casing, which cam face 1s adapted to cotiperatewith portions of the valve, whereby said valve may be opened or closedby the mere turning of the stem thereof.

Still another object of the invention resides in providing a devlcewhlch is extremely simple in construction,lnexpenslve to manufacture,andione which is very eliicient and useful inoperation.

With these and other objects in View, my invention consists in the novelfeatures of construction, combination and arrangement of parts as willbe hereinafter referred to and more particularly pointed out in thespecification and claims.

In the accompanying drawing formlng a part of this application, Figure 1is a longitudinal section through my improved gage cock. Fig. 2 is aside elevation of a portion of the valve casing, and, Fig. 3 is atransverse section through the device as seen on line 33, Fig. 1.

In carrying out my invention, I shall refor to the drawing in whichsimilar reference characters designate corresponding parts throughoutthe several views and in which 1 indicates a sleeve member or casing,one end of which is tapered and threaded, as shown at 2, and the bore 3of which communicates with a chamber 41 formed in the one end ofsaidcasing, that portion of the device forming said chamber being somewhatenlarged in diameter and internally threaded, as shown at 5. A shankmember or additional casing 6 having a longitudinal bore 7 therethrough,has one end thereof externally threaded, as shown at 8, and engaged Withthe internally threaded portion 5 of the chamber a, that portion of themember 6 which is threaded at 8 being reduced to form a shoulder 9 whichis adapted to abut the peripheral edge of the member 1 when said member6 is properly engaged with said sleeve member 1. The bore 7 is somewhatenlarged in diameter for a portion of its length, as shown at 10, thisenlarged portion of thebore communicating with a passage-way or the like11 formed in a lateral extension 12 of the member 6, and the innerperipheral edge of said member 6 which extends within the chamber 1, isprovided at diametrically opposite points thereon with the cavities orrecesses 13, the opposed wall of each recess being the continuation of acam surface 14-, the purpose of which will be hereinafter and morepartioularly described.

Extending longitudinally through the bore 7 is a shaft or stem 15, theinner end of which is provided with a head or valve 16' which is adaptedto be seated in the valve seat 17 formed at the outer end of theenlarged bore portion 10 of said member 6. The outer end of the stem 15is provided with a handle member or the like 18, and a coil springmember 19 which encircles said stem 15, has one end thereof contactingwith said handle member 18, while the opposite end contacts with the capmember 20 which is threaded onto thethreaded end 21 of the member 6,wherebyiit will be appreciated that the tendency of said spring to drawthe stem outwardly, will normally position the valve 16 in the seat17.The valve 16 form-' ing a head on the one end of the stem 15, projectsbeyond the inner peripheral edge of the member 6 and has extendingtransversely therethrough a pin 22 which, proj ecting beyonddiametrically opposite points on said valve, forms substantial lugsthereon adapted to enter the notches or recesses 13 in the peripheraledge of said member 6. Thus, from this construction, it will be seenthat by turning the handle member 18, which will turn the stem and valvethereon, the pin 22 contacting constantly with the cam surfaces 14, willunseat the valve 16, simultaneously drawing inwardly upon the stem 15against the tension of the spring 19. A continued turning of the handlemember 18 to position the projecting ends of the pin 22 in contact withthe flat peripheral edge of the member 6, will retain the valve in. its.

open position, due to the tension of the spring 19 thereon, but it willbe appreciated that if the valve is merely turned sufliciently to permitthe pin 19 to contact with portions of the cam surfaces 14, said valvewill readily return to its closed position through the aid of thepressure of the water or steam which may be passing through the bore 3and the tension of the spring 19. When the valve is held in its openposition, it will be seen that the water or steam, as the case a may be,may be permitted to pass from the boiler or the like through the bore ofthe member 1 into the chamber 1, from whence it will continue in itspassage through the enlarged bore 10 out through the bore 11 of thelateral extension 12.

Of course, it is possible that after constant use, portions of thedevice may become damaged to such an extent as to require repairing, andin order to permit such repair,

' i I provide the member 1 with the plug valve 23 which extendstransversely t-herethrough and has the one end threaded and engaged witha nut '24, whereby the same may be securely held in position. lVhen itis desired to effectively position this plug valve, it will only benecessary to loosen the nut 24, whereupon said plug valve may beslightly turned, and when the same has completely closed the passage-wayof the door 3, said nutmay again be turned home to described theelements secure said plug in this position. Any necessary repairs maythen be made without danger of the steamer water escaping.

From the foregoing, it will be seen that I have provided a simple,inexpensive and efficient means for carrying out the objects of theinvent-ion, and while I have particularly which are most well adapted toperform the functions set forth, it is obvious that various changes inform, proportion and in the minor details of construction may beresorted to without departing from the spirit or sacrlficing any 7 ofthe principles of the invention.

\Vhat I claim is 1. A gage cock comprising a casing provided with alongitudinal bore and having a chamber formed at one end thereof incommunication with said bore, said chamber being internally threaded, anadditional free end thereof, a spring member encircling said stembetween the handle member and the additional casing, a pin extendingthrough said valve, the projecting portions of which are adapted to beseated in the notches on the peripheral edge of said 1..

additional casing and also adapted to cooperate with the cam surfaces,and an outlet in communication with the enlarged bore portion of theadditional casing.

52. A gage cock comprising a pair of sleeve portions in threadedengagement with one another, the one sleeve portion being provided witha chamber at the engaged end thereof, the other of said sleeve portionshaving a portion of the bore enlarged and i provided with a valve seatat one end thereof, said last mentioned sleeve portion also having itsinner peripheral edge provided with notches at diametrically oppositepoints thereon and the opposed walls of said notches formed into camsurfaces, a valve adapted to be mounted in the seat referred to, a stemfor the valve extending longitudinally through the bore of the lastmentioned sleeve portion and having its outer end provided with a handlemember, a spring encircling said stem between the handle member and thereferred to sleeve, and a pin extending transversely through the valve,the projecting portions of which are adapted to be seated in saidnotches and coeperate with the cam surfaces; in the positioning ofsaid-valve.

In testimony whereof I hereunto affix my signature in the presence oftwo witnesses. CARL EDWARD ANGIER. Witnesses LLoYD M. MoCLURE, F. E.SCHNEDER.
